Designed as open standard, camera-independent lenses, the versatile LPL-mount ARRI Signature Primes offer easily customizable looks, a wide range of focal lengths, and zoom lenses to match. Like the rest of the series, the 25mm T1.8 ARRI Signature Prime covers all image sensors up to and including full-frame, large-format. This wider lens is one of 16 primes featuring organic images, attractive bokeh, subtle flaring, and a fast maximum aperture for achieving shallow depth of field. This prime lens gently softens the large-format look and produces pleasant, natural skin tones and crisp blacks. Focus falls off smoothly, highlighting your subject against its background frame.

Stockings, nets, and voile can be used to create custom diffusion and other effects when mounted in the Signature Prime's magnetic rear net holder. Eleven iris blades produce smooth, rounded bokeh effects, and a telecentric design minimizes breathing. The integrated LDS-2 lens data system is backwards-compatible with ARRI's LDS-1 and communicates with Cooke's /i Technology.

Constructed with magnesium housings and aluminum gear rings, each Signature Prime is lightweight, water-resistant, and features focus marks in feet. Anti-reflective coatings, light baffles, and light traps help to minimize any internal barrel flare. Should a stunt go awry, or your camera rig be otherwise damaged, the lens mechanics are designed for easier access at an ARRI service center. The 25mm ARRI Signature Prime focuses down to 5.1" from the lens front, and features a light weight of ${Wt} pounds, and a compact length of 7".

Which is better cooke s/8i ff lens or Arri signature prime lens
Asked by: Sahil
Cooke and ARRI are two of the finest cinema lens manufacturers in the world. Either would do the job they are call upon to do, and do it with exemplary panache. To decide which one to use, you need to find out what the shot or the entire production requires of its lenses. You then do tests with both lenses to determine which one works. It can be said that Cooke's exhibit a warmth that is very complimentary to people, particularly faces. Arri lenses, like Zeiss, exhibit a cooler, very color accurate tone. These two colors are very subtle and you have to look for them.

If I get an LPL adapter for my Nikon Z6, will this lens cover the full frame and work with the camera?
Asked by: Richard
yes if you are able to mount an LPL lens (this lens) on a Nikon Z the lens will cover the the sensor and more as the image circle for the lens is designed for the ARRI LF cameras which are significantly larger that FF photo sensors
